Ответ:
Length = 17 feet, Width = 5 feet
Step-by-step explanation:
Given:
The area of a rectangular wall of a barn is 85 square feet.
Its length is 12 feet longer than the width.
Question asked:
Find the length and width of the wall of the barn.
Solution:
Let width of a rectangular wall of a barn =![x](/tpl/images/0565/2849/a0e3f.png)
As length is 12 feet longer than the width.
Length of a rectangular wall of a barn =![12+x](/tpl/images/0565/2849/ff78d.png)
As we know:
Subtracting both sides by 85
As width can never be in negative, hence width of a rectangular wall of a barn =
= 5 feet
Length of a rectangular wall of a barn =![12+x=12+5=17\ feet](/tpl/images/0565/2849/6a8cf.png)
Therefore, length and width of the wall of the barn is 17 feet and 5 feet respectively.
